SOLE AND STITCH REMOVING MACHINE.

Application filed August 6, 1923. Serial No. 655,990.

To all whom it may concern:

Be it known that I, l iiun A. Warm, a citizen of the United States, residing at Los Anigeles, in the county of Los Angeles and irltate of California, have invented certain new and useful Improvements in Sole and Stitch Removing Machines, of which the following is a specification.

This invention relates to a sole and stitch removing machine, designed primarily for use in connection with shoe repairing work, although it is to be understood that the machine can be employed for any purposes wherein it is found applicable, and the in vention has for its object to provide, in a manner as hereinafter set forth, a machine including a sole removing element and an old stitch removing element, operating synchronously for simultaneously disconnecting a sole from a welt and for removing the old stitches also from the welt.

A further object if the invention is to provide a machine, in a manner as hereinafter set forth and for the purpose referred to, including a cutter or knife element for severing a sole from. a welt and further including a thread remover operating synchronously with the knife or cutter element for removing the old stitching from the welt as the sole is being severed therefrom, whereby a worn sole and its attached threads can be quickly removed from a welt to expedite the operation of the repairing of the shoe.

Further objects of the invention are to provide a machine, in a manner as hereinafter referred to and for the purpose set forth, which is simple in its construction and arrangement, strong, durable, compact, thoroughly etlicient and convenient in its use, readily assembled and comparatively inexpensive to set up.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically do scribed and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a sole and the head of the machine illustrating the sole removing element as well as the thread removing element.

Figure 3 is an end View of the head illustrating the sole and thread removing elements.

Figure 4: is a longitudinal sectional view, ln-oken away, of the head of the machine.

Referring to the drawings in detail, 1 denotes a standard of any suitable type and which is provided at its upper end with a pair of bearings 2, 3. Projecting laterally from the standard 1 below the top thereof, is a support d, for an electric motor 5, which is connected in any suitable manner with a source of electrical energy. The motor shaft is indicated at 6 and is provided with a grooved pulley 7, for driving a transmission belt 8, which is trained over a grooved pulley 9, car *ied on the inner end of the operating shaft 10 of the machine. The shaft 10 is mounted in the bearings 2, 3, and pros from each end thereof, and the outer end of said shaft lO is provided with an annular head 11 of materially greater diameter than the diameter of the shaft.

The standard 1 is formed with a lateral arm 12, having its outer end enlarged, as at 13, and which is disposed in parallelism with respect to the shaft 10, and secured to the enlarged end 1.3 is the flanged end 141- of a guard member 15, provided with an opening 16, for the passage of the head 11 of the shaft 10. The end terminal portion 17 of the member 15, is offset with respect to the remaining portion of said member 15, whereby the portion 17 will be offset in a direction towards the bearing 3. The offset terminal portion 1'? has a part of one side edge thereof, as indicated at 18, disposed at an inward inclination, ant the other side edge has a part thereof, as indicated at 19, extending at an inward inclination, but the inclination is less than the inclination of the part 18,whereby the end edge 20 of the member 15 will be disposed eccentrically with respect to the lengthwise center of said member 15. The inclined parts 18 and 19 of the side edges of the member 15 provide a tapered free terminal for the member15 and which is eccentrically disposed, and furthermore which gradually reduces in thickness toter between the trated by way of example, as

ing element and which element consists of a disk wards the end of said tapered terminal to provide What may be termed a sharp tapered terminal portion so that the latter can enwelt and the sole when the sole is being severed from the welt and which furthermore will protect injury to the Welt during the operation of the knife or cutter element to be presently referred to.

Fixedly secured, by the hold-fast device 21, to the shaft 10, is a collar 22, which is arranged in close proximity to the bearing 3 and rotates with the shaft 10. Extending laterally from the shaft 10 through the collar 22, as well as projecting from the latter, is a pin'23, which has its outer end positioned within a lengthwise slot 24, formed in the inner end of a cup-shaped cylindrical carrier 25. The carrier 25 surrounds the collar 22 and has one end formed with an opening 26 for the passage of the shaft 10. Surrounding the shaft 10 and interposed between the collar 22 and that end of the carrier 2 5 which is provided with the opening 26, is an expanding element 27 which is illusa body of rubber, but if desired the said element 27 may be constructed of a coiled spring. he function of the element 27 is to normally shift the carrier 25 in a direction towards the head 11 of the shaft 10. The carrier 25 is provided with an opening 28, to permit of access being had to the holdfast device 21. Secured to one end of the carrier 25, by thehold-fast devices 29, is the stitch removis interposed between the carrier 25 and the head 11, and is further maintained in permanent contact with the head 11 through the medium of the expandingj element 27. The stitch removing 30 provided with a series of tangentially disposed oval-shaped slots 31, having formed integral with one edge thereof a semi-oval shaped rib 32 which acts against the welt to remove the stitching therefrom after the cutter element to be presently referred to has severed the stitching between the sole and the welt. The stitch removing element operates againstthat face of the welt opposite that face which is secured to the sole and from which the sole is disconnected.

The pin 23 provides for the bodily rotating of the carrier 25 with the shaft 10, and as the I stitch removing element is fixedly secured to one end of the carrier 25, it is ob vious that said element rotates with the shaft and carrier. The stitch removing elementis spaced a substantial distance from the guard member.

Theknife or cutter element consists of an oscillatory bar 33, pivotally connected as at 3* to the enlarged outer end 13 of the arm 12. The bar 33 is provided near its free end with an oval-shaped slot 35 through. which extends a headed pin36, which is secured to the head 11 of the shaft '10. The pin 36 is eccentrically disposed with respect to the. axis of the head 11. Adjustably connected to the free end of the bar 33, is a cutter member or knife 37, having an augularly disposed cutting terminal 39 which operate-1 between the welt and the sole for the purpose of severing the stitching whereby the sole is disconnected from the welt and the. welt during the severing of the Stitching by the cutting terminal is protected through i he medium of the guard member to.

The shoe is positioned with respect to the cutter element and stitch removing element in such manner that the stitch removing element will operate against that face of the welt opposite the face to which the sole is attached for the purpose of removing the old stitching when the cutter element se vers the stitching to disconnect the sole. The ribs acting against the loose stitching will quickly remove the same from the welt i111 mediately upon the severing of the stitching by the knife. When the shoe i positioned with respect to the machine, for the purpose of removing the sole, the cutting terminal. 38 is arranged to extend between the sole and the welt for the purpose of severing the stitching, and owing to the oscillation of the bar 33, the said cutting terminal 38 will act to sever the stitching thereby disconnecting the sole from the welt.

The stitch removing element synchronously rotates during the oscillatory movement of the cutter element, due to the fact. that both elements are driven from the shaft: It) simultaneously.

Although the preferred embodiment of the invention is as described and shown, yet it is to be understood that changes in the details of construction can be had which will fall within the light of the invention as claimed.
